Abstract

RFCs 6513, 6514, and others describe protocols and procedures that a
Service Provider (SP) may deploy in order to offer Multicast Virtual
Private Network (Multicast VPN or MVPN) service to its customers.
Some of these procedures use BGP to distribute VPN-specific multicast
routing information across a backbone network. With a small number
of relatively minor modifications, the same BGP procedures can also
be used to distribute multicast routing information that is not
specific to any VPN. Multicast that is outside the context of a VPN
is known as "Global Table Multicast", or sometimes simply as
"Internet multicast". In this document, we describe the
modifications that are needed to use the BGP-MVPN procedures for
Global Table Multicast.
